Showy dragonflies are being driven extinct by warming and wildfire
Year: 2025
Rising temperatures may disrupt reproduction before becoming lethal; thus mating traits could define species vulnerability to warming. Here, using >1,600 estimates of local extinction for 60 dragonfly species, we show that species with mating-associated wing ornamentation experienced more extinctions and lost more habitat under warming and following wildfire burn than non-ornamented species. By contrast, sensitivity was not affected by ecological traits, such as thermal limits, habitat specialization or body size.

Major changes in climate, vegetation, and ecological resilience in recent decades suggest climate smart management strategies for western US dryland shrublands and woodlands
Year: 2025
BackgroundCatastrophic wildfire has escalated across the globe in recent decades with devastating consequences for human communities and native ecosystems. Global change processes, including climate warming and land use practices, are altering fuels, fire risk, and ecosystem recovery. Managing ecosystems to reduce fire risk and prevent conversion to undesirable alternative states requires knowledge of the ecological conditions of ecosystems, trajectories of change, and drivers of those changes. We developed an approach for evaluating ongoing changes in climate and vegetation and using that…
